Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

EXECUTIVE SUMMARY Title 12 of Article 27 of the Environmental Conservation Law (Title 12), adopted as the Clean Water Infrastructure Act of 2017, established a program for the investigation and remediation of certain solid waste sites that may be impacting or contaminating drinking water supplies. This report to the Governor and the Legislature documents the activities and findings of the investigation activities that have been conducted through December 2020 and presents a comprehensive plan to mitigate and/or remediate identified sites where drinking water resources have been impacted.

The objective of Title 12 is to establish a solid waste site priority list of mitigation and remedial activities to address sites causing, or substantially contributing to, impairments of drinking water quality. The primary focus under Title 12 is inactive solid waste disposal sites, primarily landfills, and their potential impact on New York’s drinking water resources from site‐related contaminants, with a focus on emerging contaminants, including per‐ and polyfluoroalkyl substances (PFAS) and 1,4‐dioxane. These compounds are human‐made chemicals that have been widely used in industrial and commercial processes and products (e.g., firefighting foams, carpeting, waterproof clothing), and are now being found in groundwater and drinking water sources across the United States.

Implementation and management of activities conducted to date under Title 12, referred to as the Inactive Landfill Initiative (ILI) Program, include:

1. Creation of an inventory of data on the inactive solid waste disposal sites and landfills within the State, including assembling available records, conducting site visits to gather basic site information, and confirmation of GPS (global positioning system) coordinates. 2. Development of a priority ranking system to assess the possible likelihood that an inactive landfill could be contributing to impacts to drinking water. 3. Completion of preliminary groundwater investigations at sites determined to have the highest potential to impact drinking water resources (herein referred to as “Investigation Sites”), per the ranking system developed for the program. 4. Sampling at potential receptor points (i.e., private and public drinking water supply wells) for inactive landfills where impacts to groundwater were identified. 5. Initiation of further investigations and mitigation/remediation activities, as warranted, based on the results of groundwater and drinking water supply sampling. The following Table ES.1 summarizes ongoing and completed activities through December 2020 under the ILI Program.

Overall, the results of this investigation have shown that the presence of PFAS compounds in groundwater near inactive landfill facilities is relatively common. Levels of perfluorooctanoic acid (PFOA) and/or perfluorooctanesulfonic acid (PFOS) in groundwater were found at concentrations exceeding the New York State maximum contaminant levels (MCLs) in drinking water (10r parts pe trillion (ppt) for each of PFOA and PFOS) at 77%, and exceeding the United States Environmental Protection Agency (USEPA) lifetime health advisory for drinking water of 70 ppt for PFOA+PFOS at 45%, of the 262 landfills investigated through December 2020 (Figure ES.1).

Comparatively, the results of the investigations conducted under the ILI Program show a less frequent distribution of 1,4‐dioxane in groundwater. As shown in the Figure ES.2, 1,4‐dioxane was found at levels exceeding the NYS MCL (1 part per billion (ppb)) at 29% of the landfills investigated and exceeding the USEPA 1 x 10‐6 cancer risk level (0.35 ppb) at 41% of the 262 landfills investigated through December 2020. Overall, 1,4‐dioxane was not found above the detection limit at approximately 39% of the 262 landfills investigated through December 2020.

ii Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

The statistics for PFOA/PFOS and 1,4‐dioxane indicate the potential association of these compounds with the inactive landfill sites. However, as the investigations are still underway and the landfills with the highest potential risk are being investigated first, these statistics should not necessarily be considered representative of the overall inventory of sites. When encountered, landfill sites with concentrations of these emerging contaminants exceeding the NYS MCLs have been prioritized for immediate further actions to mitigate any potential impacts to downgradient sources of drinking water.

The process for conducting sampling at potential receptor points (e.g., private and public drinking water supply wells) was initiated in the vicinity of inactive landfill sites where concentrations in groundwater samples exceeded the NYS MCLs for PFOA, PFOS, and/or 1,4‐dioxane. The goal of the potential receptor sampling was to assess whether contaminants detected in groundwater samples at the landfills were present in downgradient private or public supply wells.

In addition to the 262 sites investigated through December 2020, 238 additional sites identified for groundwater investigation are in the process of being completed. In addition, water supply source sampling is being initiated at a minimum of 56 more sites. An investigation priority list included in this report outlines the prioritization and schedule for additional site investigations to be initiated based on the site ranking and other critical factors.

Through December 2020, 25 sites investigated under this ILI Program were found to have elevated groundwater or drinking water concentrations of PFOA, PFOS, and/or 1,4‐dioxane, beyond the range of most other sites. These sites were reviewed by NYSDEC to determine whether further investigations or actions were justified, and the most appropriate regulatory mechanisms through which actions should be completed. Based on this review, it was determined that these sites warranted transfer to the State Superfund program administered by the Division of Environmental Remediation (DER) for further site assessments and mitigation/remediation as needed. In addition, due to close proximity to one of these 25 sites, a 26th site investigated under the ILI Program has also been incorporated into these assessments.

iii Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

The results of the inactive landfill groundwater investigations completed through December 2020 have established that certain inactive solid waste disposal sites do have the potential to impact certain drinking water sources. Furthermore, results show that detectable levels of emerging contaminants have been found in some private wells in the vicinity of several of these sites, above existing criteria. At these locations, the Department initiated immediate response actions based on recommendations from NYSDOH. Impacted sites identified have been elevated to the Solid Waste Site Mitigation and Remediation Priority List presented within this report. Included in this list are recommendations for additional actions to further assess the impacts to certain drinking water supplies and to establish a plan to remediate and/or mitigate the impacts. Implementation of this plan has been initiated on an expedited basis, to promptly and efficiently mitigate any impacts on drinking water supplies potentially caused by these sites. Based on these findings, and the continued analysis of the contamination profile of emerging contaminants in relation to the ranking system, this Program, including expansion of the site investigation program, will continue.

Table ES.3 below outlines the proposed schedule for the initiation of additional groundwater investigations under the ILI Program, based on site ranking described in Section 2 of this report.

Table ES.3: Proposed Schedule for Initiation of Future Groundwater Investigations Under the ILI Program

Based on a statistical analysis conducted on the data collected to date in support of the development of this schedule, it is anticipated that the ILI Program will investigate and characterize a large majority of the higher priority sites by 2025. While conducting these investigations, recommendations will continue to be provided for mitigation and/or remediation for inactive sites that have the potential to impact drinking

1.0 PROGRAM BACKGROUND

1.1 TITLE 12 SUMMARY The Clean Water Infrastructure Act (CWIA) of 2017 included the addition of Title 12 (Mitigation and Remediation of Certain Solid Waste Sites and Drinking Water Contamination) to Article 27 of the Environmental Conservation Law. The law required the New York State Department of Environmental Conservation (NYSDEC), together with the NYSDOH, to develop a system to identify and prioritize, for mitigation and remediation, solid waste sites that are causing or substantially contributing to the impairment of drinking water quality which may impact public health. It further required that the NYSDEC must submit a report annually to the Governor and Legislature with a comprehensive plan designed to address solid waste sites on the mitigation and remediation priority list.

Title 12 authorized the NYSDEC to conduct preliminary groundwater investigations of high‐priority sites to assess ongoing or potential impacts to drinking water sources. Title 12 also provides authorization to NYSDEC, along with NYSDOH and individual solid waste site owners/operators, to undertake mitigation and remediation of sites or areas deemed necessary for the protection of a public drinking water supply. Consistent with the requirements of Title 12, this report establishes the priority list of all known inactive solid waste disposal sites in the state and includes a comprehensive plan designed to mitigate and/or remediate solid waste sites by NYSDEC direct action.

Under Title 12, NYSDEC has focused on inactive solid waste disposal sites, primarily landfills, and their potential impact on New York’s drinking water supply with an emphasis on emerging contaminants, including per‐ and polyfluoroalkyl substances (PFAS) and 1,4‐dioxane. These compounds are human‐made chemicals that have been widely used in industrial and commercial processes, in commercial and residential products (e.g., firefighting foams, carpeting, waterproof clothing), and are now being found in groundwater and drinking water sources across the United States.

Increased knowledge and awareness of these compounds within the environment, and the potential risks to human health, have resulted in the development of new health advisories and standards by numerous federal and state agencies within the United States. In 2016, the United States Environmental Protection Agency (USEPA) issued a lifetime health advisory (LHA) for drinking water of 70 ppt for the sum of perfluorooctanoic acid and perfluorooctanesulfonic acid (PFOA+PFOS). Additionally, USEPA has derived a drinking water concentration representing a 1 x 10‐6 cancer risk level for 1,4‐dioxane of 0.35 ppb. Within New York State, maximum contaminant levels (MCLs) of 10 ppt each for PFOA and PFOS, and 1 ppb for 1,4‐dioxane in drinking water were promulgated on August 26,2020, which are amongst the lowest within the United States. The NYS MCL for 1,4‐dioxane represents the first drinking water standard for the chemical within the United States.

Implementation and management of activities conducted under Title 12 herein are referred to as the Inactive Landfill Initiative (ILI) Program, which is being conducted by the NYSDEC Division of Materials Management (DMM). This initiative includes solid waste sites or inactive landfills within New York where illegal disposal of solid waste is known or suspected to have occurred, as well as inactive landfills.

1.2 PROGRAM GOALS The ILI Program encompasses all efforts undertaken by NYSDEC to inventory and evaluate all known inactive landfills within New York State for potential drinking water and/or groundwater impacts. The overall goal of the ILI Program is to establish the Solid Waste Site Mitigation and Remediation Priority List and a comprehensive plan to mitigate and remediate impacted sites. This priority list represents the inactive landfills which have been shown, through the results of the activities conducted within this Program, to impact drinking water sources.

1.3 EXECUTION STRATEGY Several tasks were identified to gather the information pertaining to the inactive landfills within New York State that would be necessary to meet the ILI Program goals, including:

1. Compilation of data on the inactive solid waste disposal sites and landfills within the State, including assembly of available records, site visits to gather basic site information, and confirmation of global positioning system (GPS) coordinates. Review of existing data, sampling, and/or historical investigations to identify site operational information and characteristics and determine whether impacts to groundwater have been documented in the past. 2. Development of a ranking system which uses the key information gathered during Task 1 to yield a risk score to represent the relative likelihood that an inactive landfill could impact drinking water resources. 3. Completion of preliminary groundwater investigations at the higher‐ranking inactive landfills, with special emphasis placed on threats to drinking water resources and inactive landfills that have not been fully investigated or remediated under NYSDEC regulatory programs. 4. Completion of sampling at potential receptor points (i.e., private and public drinking water supply wells) for inactive landfills where impacts to groundwater were identified. 5. Conduction of further investigations and mitigation/remediation activities as warranted based on the results of groundwater and potential receptor sampling. To support the implementation of these activities, NYSDEC DMM engaged an engineering consultant (Parsons & its subcontractor OBG) under NYSDEC’s Standby Engineering Contract #D007623. Implementation of the activities above is currently being managed and executed jointly by the Parsons team and NYSDEC personnel under Standby Engineering Contract #D009811.

Through December 2020, 1,901 inactive landfills have been identified and assessed under this Program, as shown in attached Figure 1.1.

2.0 PROGRAM EXECUTION

2.1 SCOPE AND OVERVIEW OF COMPLETED ACTIVITIES Initial activities for the ILI Program began in 2016, prior to passage of the CWIA, with NYSDEC staff accumulating site information and initiating field inspections of identified inactive landfills, with an initial focus on NYSDEC Region 1 sites (Nassau and Suffolk Counties). In September 2017, through the engagement of the Parsons & OBG team and continued collaboration with NYSDEC staff, procedures and activities were formalized for consistency and efficiency, and additional resources were allocated to facilitate rapid progress of the Program. As a result, a substantial amount of data and information has been amassed, providing the NYSDEC with a comprehensive inventory of inactive landfills within New York State for use in assessing the potential emerging contaminant risk these facilities may pose to drinking water. Key metrics and activities completed under the ILI Program are summarized in Table 2.1 below. A brief discussion of these activities, including their goals, is provided in the remainder of this section.

Table 2.1: Summary of Ongoing and Completed Activities Within the ILI Program

2.2 SITE IDENTIFICATION AND RESEARCH GOALS Background research was conducted for each of the inactive landfills identified by NYSDEC. The goal of this research was to gather pertinent site information (e.g., landfill location, operational history, current ownership, and the nature of disposed materials) into a comprehensive database of the inactive landfills within New York. Background information obtained during this step was used to help determine which inactive landfills would undergo further investigation, as described in Section 2.5. Ultimately, the goal of this process includes establishing a comprehensive state‐wide database of knowledge and information pertaining to the inactive landfills within New York State for future use, which can be linked to the NYSDEC EQUIS™ system that houses the environmental monitoring data.

3 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

PROCESS The collection and consolidation of background information typically consisted of examining files available in the regional NYSDEC offices (e.g., Local Solid Waste Management Plans), as well as utilizing other sources, including the publicly available Division of Environmental Remediation (DER) database of inactive hazardous waste sites, internet search engines, and discussions with local officials or property owners familiar with a particular inactive landfill’s history. During this process, pertinent site documents were reviewed, including site maps, boring logs, previously collected analytical data, and monitoring/status reports. The information obtained during this process was often sufficient ______: Historical Imagery used to verify to positively identify the locations of landfills. Figure 2.1 landfill location and extents below summarizes the number of landfills identified and Photo 2.1: Historical imagery used to verify landfill investigated as part of this step of the Program. locations and extent If more information was needed to locate a site, additional resources were employed, including historical aerial imagery (Photo 2.1), discussions with municipal officials, historical newspaper articles, and tax parcel information and assessment rolls from the municipalities in which the landfills were located. Although the ILI Program includes inactive landfills that were permitted and regulated at the time of their operation, many others were operated decades ago prior to the formation of the Department. As a result, there was often little accessible information available for these sites, and their precise locations were often uncertain. Therefore, to create a reference point during the site identification and research step, confirmed GPS coordinates were established for each inactive landfill. This and other available background information (e.g., tax parcel information, ownership contact information) were consolidated within the ILI comprehensive database.

2.3 SITE INSPECTIONS GOALS Site inspections were conducted to verify the location and existence of each inactive landfill, assess the current conditions, locate monitoring wells (if present), and obtain other information needed for ranking. PROCESS Access for site inspections was generally granted by property owners via phone calls, written correspondence, or through 10‐day‐notice access letters prepared by the NYSDEC Office of General Counsel. For landfills where NYSDEC staff had recently (generally within 5 years) conducted an inspection, information from that inspection was used for the ranking evaluation. Site inspections generally consisted of traversing the landfill property, observing conditions (Photos 2.2, 2.3), identifying the presence of exposed waste or seeps, visually inspecting cap/cover systems (if applicable), collecting GPS coordinates, and taking site photographs as documentation of conditions. Inspections were conducted by NYSDEC, Parsons, and OBG staff. Property Photo 2.2: Conditions typically found owners were typically offered the opportunity to during site inspections participate in the site inspection. The results of each inspection were documented in a site inspection report, which included photos, observations, and a site map. The landfill conditions varied widely, from properly closed and well‐maintained to neglected and overgrown with large amounts of exposed waste material. Through December 2020, 20 sites remain to be inspected primarily due to the process of securing necessary access Photo 2.3: Example of a seep found to the site. during a landfill site inspection. 2.4 RANKING GOALS A systematic ranking strategy was developed to establish a relative priority for further investigations, based on potential risk from inactive landfills to groundwater and drinking water, and for use in development of the priority list. The ranking system was designed to be used with the landfill‐specific information gathered during the site identification and research, and during site inspection activities, described in Sections 2.2 and 2.3 respectively. This ranking system was designed to be objective, based on available and verifiable information for each landfill, with the understanding that historical information may be limited for many sites. The goal of the ranking system was to identify the landfills that have a

5 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan higher potential to discharge contaminants, including emerging contaminants, to groundwater that could potentially impact sources of drinking water. The finalized ranking system is included in Appendix A. PROCESS The ranking system consists of four overall categories, each containing a series of criteria. These categories include:

 Proximity of Potential Receptors – This category consists of four criteria corresponding to the landfill’s proximity to potential receptors (i.e., distance to any potential receptors, distance to residential areas with private wells, distance to residential areas with public water supplies, and distance to known public supply wells).  Landfill Characteristics – This category consists of four criteria corresponding to the physical aspects of the landfill (i.e., nature of waste, type of landfill cap, landfill slope, total size).  Geologic Setting – This category consists of two criteria related to the specific geologic characteristics of the landfill’s location which would influence the potential migration of contaminants originating from the landfill (i.e., permeability, depth to groundwater).  Current Condition – This category consists of three criteria related to recent documented conditions of the landfill (i.e., presence of seeps within the landfill cap, results of historical sampling, condition of the landfill cap). Each criterion within the four categories were given a relative weighting score corresponding to the potential risk contribution to drinking water resources. Overall, the criteria weighting emphasized inactive landfill proximity to locations where groundwater is used for drinking water purposes (i.e., public supply wells, private wells, sole‐source or primary aquifers) and to conditions favorable for migration of contaminants from the landfills. These risk factors were determined to be most significant and could be assessed with a high degree of certainty.

In addition to the categories above, a series of additional criteria were established based on yes/no answers to critical risk factors (e.g., Is the landfill located within a sole source 600 580 aquifer?). These criteria included opportunities for 500 442 both the addition and ~ 2l 400 subtraction of points from iii 0 325 the overall score, ci 300 depending on whether the ~ u> C criteria would increase or ~:, 200 er 155 157 decrease the relative ~ u. 117 potential that a site could 100 57 have to impact a drinking 41 4 water supply.

Figure 2.2: Results of Inactive Landfill Ranking In application, however, actual landfill scores fell within a much narrower range (‐8 to 84). Figure 2.2

6 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan depicts the results of ranking of 1,881 accessible sites through December 2020. The remaining site rankings will be updated as site inspections are completed.

2.5 GROUNDWATER INVESTIGATION GOALS Groundwater investigations (Photos 2.4, 2.5) began in 2017 at inactive landfills identified to be potential threats to drinking water sources, with the goal of evaluating groundwater quality immediately downgradient of landfills. The groundwater investigations generally include collecting an average of three groundwater samples (including samples from both upgradient and downgradient of the landfill sites) to obtain a preliminary characterization of groundwater quality. Through December 2020, investigations have been conducted at 262 identified priority landfill sites, and an additional 238 investigations are planned to be completed, pending finalization of the scope details and property access. An additional 63 sites that would have otherwise been included on the investigation list are being evaluated and advanced under other regulatory programs. PROCESS Prior to the finalization of the ranking system, landfills were initially selected for investigation through recommendations by NYSDEC staff, based on site knowledge and history. Following finalization of the ranking system, landfills with a ranking score greater than 53, or landfills with certain strongly correlating characteristics discussed in Section 3.3, were identified for groundwater investigations. Some of the landfills initially chosen for investigations by NYSDEC staff received a ranking score below these thresholds, which allowed for landfills with a wide range of ranking scores to be investigated, and thus helped to assess the effectiveness of the ranking system.

To drive consistency between site investigations, several governing Program documents were prepared and reviewed/approved by NYSDEC and NYSDOH. These included a Field Activities Plan, a Quality Assurance Project Plan, and a Health and Photo 2.4: Monitoring well installation Safety Plan. These documents defined the sampling at an inactive landfill. methods and quality procedures and were prepared to be consistent with current industry knowledge and practices associated with PFAS and 1,4‐dioxane investigations, including implementation of specific procedures to prevent inadvertent introduction of PFAS and 1,4‐dioxane from clothing and other sampling equipment and associated supplies.

Site‐specific work plans are prepared to outline the specific approach for each landfill groundwater investigation. These work plans are reviewed and approved by NYSDEC staff before investigations are

7 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan conducted. Access to perform the groundwater investigations are typically obtained by executing a NYSDEC access agreement with the property owner.

Samples are submitted to National Environmental Laboratory Accreditation Program (NELAP) certified laboratories and analyzed for a suite of parameters, including PFAS, 1,4‐dioxane, metals, volatile organic compounds (VOCs), and other parameters typically found in landfill leachate. All data results are validated by a NYSDEC‐ approved chemist. Validated results are compared to water quality standards and other criteria identified in 6 NYCRR of the State of New York Part 703 as Class GA, and the NYS MCLs for PFOA and PFOS, and 1,4‐dioxane. Field activities and associated data generated are summarized in Field Activity Summary Reports which are submitted to the Photo 2.5: Typical groundwater NYSDEC staff for review and approval. Investigation sampling setup. abstracts for groundwater investigations completed through this initiative are also prepared, which briefly summarize background site information, investigation activities completed, and analytical results.

2.6 DRINKING WATER SAMPLING GOALS Drinking water sampling is conducted for identified and accessible receptors in proximity to inactive landfill sites where concentrations in groundwater samples exceeded the NYS MCLs for PFOA, PFOS, and/or 1,4‐dioxane (Photo 2.6). The goal of the drinking water sampling is to assess whether contaminants detected in groundwater samples at the landfills are present in downgradient private or public supply wells. PROCESS Standard operating procedures were developed in accordance with NYSDOH requirements for private and public supply well sampling.

Following validation of the results from the groundwater investigations described in Section 2.5, sites with groundwater concentrations exceeding the NYS MCLs for PFOA, PFOS, and/or 1,4‐ dioxane are identified for drinking water sampling. A conservative hydraulic flow direction analysis is completed at each site to identify private and public supply wells downgradient and within one‐quarter mile of the site. These wells and corresponding parcels are compiled in a “focus list” for each site. Each focus list is subsequently reviewed by NYSDOH and the appropriate local health regulatory agency for Photo 2.6: Typical drinking water comparison to their records. Upon finalization of the focus lists, sampling event. reflecting input from NYSDOH and local health agencies, letters are mailed to individual residents and property owners (see example

letter Photo 2.7), with instructions on how to contact the NYSDEC to schedule a time for collecting samples from their drinking water well. Appointments are subsequently made with responding residents and property owners. Typically, second and third attempts (including leaving hang tags at doors) to contact individual residents and property owners are made, to maximize the number of samples collected. Overall, through December 2020, approximately 50% of residents and property owners have responded to date to the offer to sample their well.

Collected samples are sent to a NELAP‐certified laboratory for analysis. Following receipt of the analytical results from the drinking water sampling, NYSDOH reviews and disseminates the data to property owners and conveys recommendations to NYSDEC. In several instances, the NYSDEC has offered and supplied alternate water supplies to residents where impacted drinking water supplies were identified.

3.0 PROGRAM RESULTS / STATUS Through December 2020, 563 sites were identified for groundwater investigation, of which 262 have been completed. The groundwater investigation results were evaluated for comparison to Class GA Water Quality Criteria, and to the NYS MCLs for PFOA, PFOS, and 1,4‐dioxane. Additionally, a detailed statistical assessment was conducted of analytical results in relation to site rank (based on the ranking system) to determine trends which could be useful in the decision‐making process associated with the overall scope of Title 12, and potentially for improving the ranking process used for site prioritization. The results of these trends, analyses, and potential application for assessment of the ILI goals, are discussed in the following subsections.

3.1 GROUNDWATER SAMPLING RESULTS Figure 3.1 presents an overall summary of the findings of the groundwater investigations _ 3% completed through December 2020 under the ILI ■ Non-Detect Program. Overall, the results of this investigation to date have shown that the presence of PFAS ■ PFOA, PFOS < 10 compounds in groundwater at inactive landfill PFOA and/or facilities is relatively common. As shown, PFOS >10, maximum levels of PFOA and/or PFOS in PFOA+PFOS <70 • PFOA+PFOS > 70 groundwater at concentrations exceeding the ppt NYS MCLs (PFOA and/or PFOS > 10 ppt) were found at 77% of the 262 landfills investigated. Maximum levels of PFOA+PFOS in groundwater at Figure 3.1: Maximum PFOA / PFOS Concentrations in concentrations exceeding the USEPA drinking Groundwater at Sampled Inactive Landfills water LHA (70 ppt) were found at 45% of the 262 landfills investigated.

Figure 3.2 presents the maximum PFOA+PFOS concentrations in groundwater at the landfills investigated in the ILI Program, demonstrating the range of results. Within this graphic, each blue marker represents the maximum result from each of the investigated landfills. In addition, attached Figures 3.3 and 3.4 (see end of Section 3) present the PFOA and/or PFOS data on both a state‐wide and regional basis.

The comparison of these groundwater concentrations is to advisory values or proposed standards for drinking water. The NYS MCLs for drinking water values have been used while groundwater standards for these emerging contaminants are developed.

Comparatively, the results of the groundwater investigations conducted at landfills under the ILI Program show a less‐frequent distribution of 1,4‐ dioxane in groundwater. As shown in Figure 3.5, ■ Non-Detect

1,4‐dioxane was not found above the detection ■ < 0.35 ppb limit at approximately 39% of the 262 landfills 0.35 - 1 ppb investigated. Overall, 1,4‐dioxane was found at ■ > lppb levels exceeding the NYS MCL (1 ppb) at 29% of the 262 landfills investigated and exceeding the USEPA 1 x 10‐6 cancer risk level (0.35 ppb) at 41% of the landfills through December 2020.

Within this graphic, each blue marker represents the maximum result from each of the investigated landfills. In addition, attached Figures 3.7d an 3.8 (see end of Section 3) show these results presented on a state‐wide basis. Overall, no correlation between the presence of PFAS compounds and 1,4‐dioxane could be drawn.

The statistics for PFOA+PFOS and 1,4‐dioxane discussed indicate the potential association of these compounds with the inactive landfill sites. However, as the investigations are still ongoing, and areas with the greatest potential risks are being prioritized for investigations, these statistics are likely to change, and may not be indicative of the overall inventory of sites.

Typical leachate parameters were commonly detected through site groundwater investigations. Additionally, metals typically present in groundwater within New York State (e.g., iron, manganese) were routinely found in samples during the site investigations conducted. Other parameters, such as VOC compounds, were infrequently detected in groundwater. However, the prevalence of these compounds varied from site to site, and no definitive statewide or regional trends were noted.

Detected compounds (e.g., PFAS, 1,4‐dioxane, VOCs, metals) generally occurred along with elevated levels of parameters commonly associated with landfill leachate (e.g., ammonia, chemical oxygen demand). Furthermore, for nearly all inactive landfill sites, elevated concentrations of chemical parameters found in downgradient locations were not found (or were found at significantly lower concentrations) in upgradient locations. These factors would be consistent with the source of groundwater impacts found being predominately due to the inactive landfills investigated, as opposed to an unidentified background source.

3.2 DRINKING WATER SAMPLING RESULTS Through December 2020, drinking water sampling was conducted in the vicinity of 96 sites under the ILI Program, which included the canvassing of nearly Total Water Supply Sources Solicited 1434 1,450 private supply wells. The key statistics Water Supply Sources Sampled* 698 pertaining to the drinking water sampling are PFOA and PFOS Not Detected 459 presented in Table 3.1. This table outlines the PFOA and PFOS Less Than 10 ppt 169 number of private residences canvassed for PFOA and/or PFOS Greater Than 10 ppt 67 sampling, the number of residences sampled 1,4 Dioxane Not Detected 186 based on responsiveness, and an overview of the 1,4-Dioxane Less Than 0.35 ppb 107 analytical results. Based on the groundwater 1,4-Dioxane Greater Than 0.35 ppb, Less Than investigation results through December 2020, 1 ppb 21 drinking water sampling is being planned for at 1,4-Dioxane Greater Than 1 ppb 14 * - Based on results of groundwater investigations at least an additional 56 sites, which will encompass each landfill, both PFOA/PFOS and 1,4 dioxane were not the canvassing of more than 2400 private supply sampled at all locations wells. Table 3.1: Drinking Water Supply Sampling Summary Through December 2020, 67 of the private drinking water wells sampled under the ILI Program have exceeded the NYS MCLs for PFOA and/or PFOS, and 14 exceeded the NYS MCL for 1,4‐dioxane.

Following receipt of groundwater investigation data for the Gerald Wright site, Westhampton Transfer Station, Brookhaven Aggregates, Morabito / VIP Industries (VID Industries) and the Damascus Road Landfill (Suffolk County), the SCDHS was consulted during the sample planning process. Following consultation between NYSDEC, NYSDOH, and SCDHS, the SCDHS canvassed and sampled private residences for these sites. This sampling was conducted by SCDHS public health sanitarians. The laboratory analysis was completed by the laboratory under contract by NYSDEC for the ILI Program.

Four other sites within Suffolk County, where PFOA and/or PFOS compounds were found in groundwater at concentrations greater than the NYS MCLs, fell within areas of ongoing studies being conducted by Suffolk County. These four sites included the Hampton Bays Transfer Station site, the Old Smithtown Landfill, the Quiogue SLF / Old Quogue Landfill, and the Joseph Menafra Manufacturing Site. Investigations previously conducted at these locations included canvassing and sampling of private wells. Therefore, no additional drinking water supply sampling was conducted under the ILI Program at these sites. An additional site falling within areas of previous or ongoing studies included the Columbia Corporation (Hoosick) Landfill in Region 4. Similarly, no additional drinking water supply sampling was conducted under the ILI Program at this site.

Additionally, there were also a limited number of sites where results from the groundwater investigation showed PFOA and/or PFOS concentrations greater than the NYS MCLs; however, no potential receptors were identified. For these sites, the surrounding parcels were typically serviced by a municipal water supply.

3.3 ASSESSMENT OF RANKING SYSTEM Based on an evaluation of the data from sites investigated through December 2020, comparing analytical results with each site’s relative score generated by the ranking system, the system is working to produce

13 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan a reasonable prioritization of sites for investigation. Through December 2020, of the 203 sites investigated with a ranking score greater than 56, 46% of the sites had concentrations of PFOA+PFOS greater than 70 ppt, and 74% had concentrations of PFOA and/or PFOS greater than 10 ppt. Based on these statistics, a continuation of the prioritization of inactive solid waste disposal sites primarily based on the ranking system is justified.

A detailed review of ranking criteria vs. groundwater data for investigated sites determined that modifications of the ranking system (e.g., scoring adjustments for specific criteria) at this time would not result in a substantial improvement in the correlation of total ranking score to analytical results. However, three ranking characteristics (herein referred to as “positive factors”) were found to correlate strongly with sites with PFOA and/or PFOS concentrations greater than 10 ppt. These characteristics include waste within groundwater, history of disposal of fire‐retardant materials and/or fire‐impacted materials and debris, and history/records of issues or legitimate public complaints. The strong correlation of these positive factors to groundwater results merits additional consideration during the process of selecting future sites for additional investigations. These “positive factor sites” were prioritized for site investigations in 2019 and 2020, as shown in Table A.1.

This evaluation also assessed the correlation of 1,4‐dioxane concentrations to the ranking characteristics. Based on the data received through December 2020, no additional prevalent correlations were identified that would warrant further consideration at this time.

As additional groundwater data is obtained from investigation list sites, the ranking system and these strong correlating characteristics will be reevaluated to identify whether there are evolving trends that should be considered in the prioritization of sites for investigation in the future.

3.4 SITES REFERRED TO STATE SUPERFUND PROGRAM Following the receipt of data from site groundwater investigations, the results were reviewed by NYSDEC to determine whether further investigations or actions were warranted, and the most appropriate regulatory mechanisms through which actions should be completed. Through December 2020, pursuant to Environmental Conservation Law section 27‐1203(5), it was determined that the elevated levels of PFOA and/or PFOS found at 25 sites warranted transfer to DER for further action. Under this referral, the sites will be evaluated by DER as Class P sites, in consultation with NYSDOH, to determine whether any of these sites pose a significant threat to public health or the environment. The Class P classification is used for sites where preliminary information indicates that a site may have contamination that makes it eligible for consideration for placement on the Registry of Inactive Hazardous Waste Disposal Sites (commonly referred to as the list of State Superfund Sites). Due to proximity of a 26th site (the Joseph Menafra Manufacturing site) to the Quiogue SLF site, the two sites were investigated jointly by DER. These sites include:

 Damascus Road Landfill (Suffolk County)  Joseph Menafra Manufacturing (L&C Concrete Corp) (Suffolk County)  Morabito / VIP Industries (VID Industries) (Suffolk County)  Quiogue SLF (Old Quogue Landfill) (Suffolk County)  Castle Point VA Hospital (Dutchess County)  Fair Street (Putnam County)

3.5 ONGOING ILI ACTIVITIES REMAINING INVESTIGATION LIST SITES Through December 2020, of the 563 sites identified for groundwater investigation, 262 have been completed. An additional 238 sites are in various stages of planning and investigation and targeted for completion in 2021. For many of these, investigation plans are being developed, and once access is secured then these site investigations will proceed. Results of these groundwater investigations will be used to identify subsequent actions, as warranted, and consistent with the procedures described in Section 2 of this report. REMAINING DRINKING WATER SAMPLING SITES Of the 262 sites for which a groundwater investigation has been completed through December 2020, the groundwater analytical results at 196 sites warranted consideration of drinking water sampling. Of those 196 sites, 157 have downgradient potential receptors that have been identified, with the remaining 39 sites having no nearby potential receptors. Through December 2020, drinking water sampling has been performed at 98 of those 157 sites. For the remaining sites, focus lists are in either development or sampling is pending. For these remaining sites, completion of the drinking water sampling has been prioritized and fast‐tracked by NYSDEC and NYSDOH to be completed as rapidly as possible.

15 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

COMPLETED INVESTIGATION LIST SITES Following receipt of the analytical results from the drinking water sampling, NYSDOH reviewed and disseminated the data to property owners and conveyed recommendations to NYSDEC. Recommendations generally consisted of 1) no further action required, 2) periodic resampling/monitoring, or 3) mitigative measures such as a point‐of‐entry treatment (POET) system. For drinking water supply locations for which periodic resampling/monitoring was recommended, the resampling is being completed under the ILI Program and will continue in consultation between NYSDEC and NYSDOH. For residential locations for which the installation of POET systems was recommended, DER has been engaged to complete the system installations.

Overall, for completed investigation list sites, site‐specific recommendations have been developed based on the analytical results from site groundwater sampling and drinking water sampling (if applicable). The process by which these recommendations are developed and applied is discussed in Section 4.

4.0 CONCLUSIONS AND RECOMMENDATIONS This section summarizes the specific recommendations for the continuation of the ILI Program and further steps that are recommended based on the results received through December 2020.

4.1 ASSESSMENT OF OVERALL POTENTIAL RISK TO DRINKING WATER SOURCES The primary objectives of the ILI Program, as outlined in Title 12, are:

 Objective 1: Assess the potential risk that inactive landfills within New York State pose to drinking water resources.  Objective 2: Develop a priority list of sites requiring remediation and/or mitigation. In support of these objectives, the tasks described in Section 2 were developed to facilitate a rapid assessment of the sites which would serve as a basis for selecting sites where initial groundwater investigations could be conducted.

As a result, the identified inactive landfills within New York have been inspected and ranked, hundreds of inactive sites have been investigated, and thousands of groundwater samples have been analyzed. From these data points, preliminary conclusions can be drawn pertaining to the potential for overall risk to drinking water resources posed by inactive landfills within New York State.

Overall, groundwater at landfills containing concentrations of PFOA and/or PFOS exceeding the NYS MCLs was found at 77% of the 262 landfills investigated under the ILI Program through December 2020. The PFOA+PFOS concentrations at these sites ranged from 13.6 ppt to 11,624 ppt. The presence of 1,4‐dioxane was less frequent, with groundwater containing 1,4‐dioxane in exceedance of the NYS MCL at 29% of the 262 landfills investigated. The 1,4‐dioxane concentrations at these sites ranged from 1 to 1300 ppb.

Pertaining to Objective 1, the results of the inactive landfill groundwater investigations completed through December 2020 have established that inactive landfills do have the potential to impact drinking water sources, and that detectable levels of emerging contaminants above criteria have been found in a small number of private drinking water wells in the vicinity of these sites. Based on these findings, the ILI Program, including expansion of the site investigations, will continue. Pertaining to Objective 2, specific recommendations for the sites investigated through December 2020 and for the initiation of investigations at additional sites are outlined in this section.

4.2 SOLID WASTE SITE MITIGATION AND REMEDIATION PRIORITY RECOMMENDATIONS Based on the results from groundwater and subsequent drinking water sampling that has been conducted at sites completed to date, site‐specific recommendations for additional steps (e.g., further investigation, monitoring, remediation/mitigation) have been developed for each site. These recommendations are summarized in the attached Table A.1. Through December 2020, recommendations have been developed for 206 sites. Recommendations for an additional 56 sites were pending completion of the potential receptor sampling, and 238 sites were pending completion of the initial groundwater investigation. The Solid Waste Site Mitigation and Remediation Priority List will be regularly updated to reflect the completion of additional investigation list sites (groundwater investigations and downgradient potential receptor sampling) and to reflect any subsequent mitigation and/or remediation actions taken.

17 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

Overall, these sites fall into one of four priority groups with respect to PFOA, PFOS, and/or 1,4‐dioxane:

Group 1 ‐ Landfills with exceedances of criteria both in on‐site groundwater and in downgradient drinking water sampling

Group 2 ‐ Landfills with exceedances of criteria in on‐site groundwater but no exceedances of criteria in downgradient drinking water sampling

Group 3 ‐ Landfills with exceedances of criteria in groundwater but no potential downgradient receptors present

Group 4 ‐ Landfills determined to have no further actions required at this time

Further discussion and recommendations pertaining to these prioritization groups are presented in the following subsections and presented graphically in Figure 4.1 (see end of Section 4). PRIORITY GROUP 1 Included within this group are the sites for which exceedances of criteria in groundwater, actively used by the local community as a drinking water resource, have been identified. These sites have been allocated to Priority Group 1 of the Solid Waste Site Mitigation and Remediation Priority List, for further investigation and mitigation/remediation considerations. At these locations, the Department initiated immediate response actions based on recommendations from NYSDOH. Through December 2020, these sites include:

 Denver Avenue Landfill (Hamlet of Bayshore / Town of Islip, Suffolk County)  Gerald Wright Landfill (Deer Park / Town of Babylon, Suffolk County)  Morabito / VIP Industries (VID Industries) (Hamlet of East Patchogue, Suffolk County)  Hurley Landfill (Town of Hurley, Ulster County)  Town of Saugerties Landfill (Town of Saugerties, Ulster County)  Carmel Landfill (Town of Carmel, Putnam County)  Kent Landfill (Town of Kent, Putnam County)  Castle Point VA Hospital (Town of Wappinger, Dutchess County)  LaGrange (Town of LaGrange, Dutchess County)  Rocky Ledge (Town of North Castle, Westchester County)  Royal Carting Service (Hamlet of Hopewell Junction, Dutchess County)  Westchester Garden Center/Labriola (Hamlet of Armonk, Westchester County)  Al Rose Construction and Demolition Landfill (Town of Northumberland, Saratoga County)  Clinton County Landfill (Hamlet of Morrisonville, Clinton County)  Easton LF (Town of Easton, Washington County)  Queensbury Landfill (Town of Queensbury, Warren County)  Croghan Landfill (Town of Croghan, Lewis County) Specific recommendations for further action that have been identified in the investigation are summarized on Table A.1. These recommendations include, but may not be limited to, the following actions:

18 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

 Installing POET systems for impacted receptors, or providing an alternate water supply  Repeat monitoring of impacted receptors, per NYSDOH recommendations  Continued monitoring of landfill groundwater  Additional site characterization  Landfill mitigation/remediation  Referral to State Superfund Program if preliminary assessments indicate a potentially imminent threat In addition to the sites identified above, sites referred to State Superfund Program for further evaluation and mitigation/remediation, as described in Section 3.4, have also been included in Priority Group 1. PRIORITY GROUP 2 Included within this group are the sites for which exceedances of criteria in groundwater have been identified; however, potential receptor sampling through December 2020 has shown no impacts. These sites have been allocated to the second Priority Group of the Solid Waste Site Mitigation and Remediation Priority List. Specific recommendations for these sites include, but are not limited to, the following actions:

 Repeat monitoring of potentially impacted receptors, in accordance with NYSDOH recommendations  Continued monitoring of landfill groundwater  Mitigation/remediation considerations based on future results PRIORITY GROUP 3 Included within this group are the sites for which exceedances of criteria in groundwater have been identified; however, there are no current downgradient potential receptors. These sites have been allocated to the third Priority Group of the Solid Waste Site Mitigation and Remediation Priority List. Specific recommendations for these sites include, but may not be limited to, the following actions:

 Monitoring of housing development near the landfill for potential future receptors  Continued monitoring of landfill groundwater  Mitigation/remediation considerations based on future results PRIORITY GROUP 4 Included within this group are the sites where it has been determined that no further actions are required at this time. This includes sites where no exceedances of criteria in groundwater have been identified.

4.3 MITIGATION AND REMEDIATION PLANNING As described in Section 3.5, specific actions are being taken immediately at water supply sources when warranted. To date, these actions have included mitigation measures (e.g., POET system installation), continued monitoring, or no further action, and are being implemented on an ongoing basis.

As sites are added to the Mitigation and Remediation Priority List, they are being evaluated to determine what mitigation and/or remediation steps are warranted and effective for the observed impacts. These evaluations have initially been focused on sites in Priority Group 1, where impacts to public or private drinking water supplies have been observed. For these sites, a detailed multi‐step assessment is

19 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

conducted, including additional site investigation activities to further define the nature and extent of groundwater impacts, and engineering evaluations to identify the best mitigation and/or remediation option for the site. For sites within Priority Group 1 which have been referred to the State Superfund Program, site evaluations will be conducted by DER under the guidance of the New York State Superfund Program. For the remaining sites in Priority Group 1, site evaluations are anticipated to be conducted under the direction of DMM. As future site investigations identify additional sites to be included in Priority Group 1, detailed site evaluations will be initiated for these sites as well. Additionally, these evaluations are anticipated to extend to lower priority groups in the future. 4.4 FUTURE ILI ACTIVITIES AND SCHEDULE Based on the results of the investigations completed through December 2020, as presented within this report, investigations will continue and will be expanded to include additional sites.

Table A.2 (attached) establishes the Solid Waste Site Investigation Priority List which outlines the prioritization of additional site investigations, by year, based primarily on the site ranking. A summary of recommended investigation sites, by year, is provided below in Table 4.1. As outlined below, 182 sites have been recommended for the initiation of site investigations in 2021. The recommended 2021 investigation site list is composed of sites that are ranked between 49 and 52. The initiation of additional investigations starting in 2022 is also outlined, according to the ranking ranges presented for each year.

Table 4.1: Proposed Schedule for Initiation of Future Groundwater Investigations Under the ILI Program

4.5 FUTURE REPORTING As required in Title 12, this Comprehensive Mitigation and Remediation Plan will be updated annually. This plan will next be updated by July 1, 2021, and will include the following:

20 Inactive Landfill Initiative Comprehensive Mitigation & Remediation Plan

 An updated Solid Waste Site Mitigation and Remediation Priority List, including updates based on further characterization, mitigation, and/or remediation activities, and additional sites identified from investigations initiated following the submittal of this report  Updated statistical analyses to further assess the potential risk to drinking water resources  Updated recommendations for further investigations and other activities associated with the ILI Program

APPENDIX A

RANKING SYSTEM

Proposed Statewide Inactive Landfill Ranking Criteria Inactive Landfill Initiative Program New York State Department of Environmental Conservation Division of Materials Management

Proximity to Potential Receptors (as measured from perimeter)

1. Proximity to nearest receptors (homes, businesses, etc.). This has a weighting factor of 3. This criterion accounts for situations where residences have been built over, or near, a landfill. Also accounts for exposure pathways in addition to groundwater (e.g., vapor intrusion).

Score Answer 0 > 0.50 miles 3 > 0.25 to < 0.5 miles 6 < 0.25 miles 9 Within waste limits

2. Distance to public supply wells. This criterion has a weighting factor of 3. Accounts for scenarios where residents are obtaining water from a community /public supply well near a landfill.

Score Answer 0 > 1.0 mile 3 0.5 to 1 mile 6 > 0.25 to < 0.5 miles 9 < 0.25 miles

3. Distance to residential areas without public water supply available. This has a weighting factor of 3. All three regional ranking systems included this criterion, using similar distance options.

Score Answer 0 > 1.0 mile 3 0.5 to 1 mile 6 0.25 to < 0.5 miles 9 < 0.25 miles

4. Distance to nearest residence with public water supply available. This has a weighting factor of 1. This criterion accounts for unique cases where residents may still be using wells even when public water supply is available (for instance, where a resident has chosen to not connect to municipal water systems). All three regional ranking systems included this criterion, using similar distance options.

Score Answer 0 > 1.0 mile 1 0.5 to 1 mile 2 0.25 to < 0.5 miles 3 < 0.25 miles

Proposed Statewide Inactive Landfill Ranking Criteria Inactive Landfill Initiative Program New York State Department of Environmental Conservation Division of Materials Management

Landfill Characteristics

1. Nature of waste (worst documented). This has a weighting factor of 1. This assesses potential impacts to receptors from known or emerging contaminant sources. All three regional ranking systems included this criterion.

Score Answer 0 Land clearing debris 1 CARBS / C&D 2 Municipal Solid Waste / Biosolids 3 Industrial waste, ash, or unknown

2. Nature of cap / cover system. This has a weighting factor of 2. Assesses the potential for potential off‐site migration of potential contaminants based on infiltration of surface water. All three regional ranking systems included this criterion.

Score Answer 0 Fully constructed / impermeable membrane cap 2 Paved / redeveloped / clay cap 4 Soil cap / vegetated 6 No cap / soil cover with waste exposed

3. Landfill size. This has a weighting factor of 3. Assesses potential impact of the volume of potential contaminant sources. Two of three regional ranking systems included this criterion.

Score Answer 0 < 1 acre 3 > 1 to < 5 acres 6 > 5 to < 50 acres 9 > 50 acres

4. Landfill slopes / grading. This has a weighting factor of 1. The focus of this criteria is on the top surface of the landfill, and reflects the potential for water pooling and infiltration.

Score Answer 0 > 10 – < 33% 1 4 – 10 % 2 0 – 4% or > 33% slopes

Proposed Statewide Inactive Landfill Ranking Criteria Inactive Landfill Initiative Program New York State Department of Environmental Conservation Division of Materials Management

Geologic Setting

1. Geologic substrate / permeability. This has a weighting factor of 3. Score reflect the higher increasing susceptibility of pervious materials underlying the landfill and the associated greater potential for offsite migration. Two of three regional ranking systems included this criterion.

Score Answer Located on low permeability glaciolacustrine silts/clays OR 0 thick glacial tills 3 Located on substrate not described above / below 6 Located on permeable glacial outwash in sands/gravel aquifers OR carbonate bedrock 9 Located in previous quarry or mine

2. Depth to groundwater. This has a weighting factor of 2. Reflects potential for releases to reach groundwater. Two of three regional ranking systems included this or an equivalent criterion.

Score Answer 0 Water below waste > 50 ft. 2 Water below waste < 50 ft. 4 Depth unknown, or potential for waste located in water 6 Waste within groundwater table

Current Conditions

1. Visible seeps / impacts / physical changes. This has a weighting factor of 2. Reflects potential for releases to reach surface water. All three regional ranking systems included this criterion.

Score Answer 0 No evidence 3 Evidence of on‐site seeps 6 Seeps / Impacts observed leaving site

2. Status of Available Monitoring Data. This has a weighting factor of 3. Accounts for the results of any valid data collected from within the site, with higher scores corresponding to previous impacts. All three regional ranking systems included this criterion. Impacts defined as exceedance of applicable criteria (Class GA, EPA advisories, etc.). Data required to be within the last five years.

Score Answer ‐20 Full analysis (including PFCs & 1,4‐dioxane) – no impacts Full analysis (including PFCs & 1,4‐dioxane) ‐ impacts limited ‐15 to common parameters (e.g., iron) ‐8 Limited analytes evaluated (e.g., no PFCs, 1,4‐dioxane) ‐ No impacts

Proposed Statewide Inactive Landfill Ranking Criteria Inactive Landfill Initiative Program New York State Department of Environmental Conservation Division of Materials Management

‐2 Limited analytes evaluated (e.g., no PFCs, 1,4‐dioxane) ‐ Impacts limited to common parameters (e.g., iron) 6 Not monitored / no recent data (within 5 years) 15 Data shows impacts with VOCs, other organic compounds or heavy metals

3. Cap Condition. This has a weighting factor of 1. This criterion accounts for condition of the cap/cover as an additional consideration of the current landfill condition and the potential for leachate generation through infiltration.

Score Answer 0 Landfill cap / cover is well vegetated/ pavement sealed 1 Landfill cap / cover has limited bare spots / pavement cracked 2 Landfill cap / cover has significant bare spots / pavement cracked 3 Landfill cap / cover shows erosion / wash outs / pavement crumbling / subbase exposed / exposed waste

Additional Criteria. These criteria provide ranking score reductions for landfills closed under modern regulations, and increases for situations where surface water/groundwater used as drinking water sources for large populations exist, or residents’ complaints reflect perceived or actual problems at the site.

Applicable? Score Description ‐10 Landfill Closed under Part 360 after 1988 (under Consent Order) Site is located within an area where current and reasonable future ‐10 site use precludes the use of groundwater ‐10 Site specific data verifies that groundwater features (gradient, flow divide, etc.) exist which eliminate pathways between site and potential receptors ‐10 Previous assessment conducted for potential impacts to drinking water supplies, and actions taken (if necessary) within past 5 years +10 History / Records of Issues or Legitimate Public Complaints as verified with Regional Staff +10 Falls within drinking water watershed or Sole Source / Primary aquifer +5 Immediately adjacent (direct flow path) to a water body / waterway +10 Disposal of fire retardant materials and/or fire impacted materials and debris (e.g., building fire)?
